A population of insects lives in the same orchard. Body color can be green or brown. Evolutionary change can be measured by shifts in trait frequency (proportions) across generations.
Trait frequency data:
- Generation 1: 70 out of 100 are green
- Generation 2: 40 out of 100 are green
- Generation 3: 20 out of 100 are green
- Generation 4: 10 out of 100 are green
Which explanation best measures evolutionary change using proportional reasoning from the data?
